When the invention is used, before the laser marking of the mobile phone shell is carried out, the distance between the laser marker 21 and the mobile phone shell needs to be adjusted according to actual needs, at the moment, the turntable 24 only needs to be held by the right hand on the front to rotate, when the turntable 24 rotates, the rotating rod 27 rotating with the turntable 24 can be driven to rotate, because one end of the rotating rod 27 is fixedly connected with the second bevel gear 28, and the second bevel gear 28 is meshed with the first bevel gear 26 fixed at the bottom end of the screw rod 25, the turntable 24 can drive the screw rod 25 to rotate, and because the external diameter of the first bevel gear 26 is larger than the external diameter of the second bevel gear 28, the mechanical principle of driving the big gear by the small gear can also achieve labor-saving effect and higher accuracy, because the lifting block 23 sliding in the fixing sleeve 22 is in threaded connection with the screw rod 25, the lifting action of the lifting block 23 can be realized by the rotation, the laser marker 21 arranged on the lifting block 23 can be driven to adjust up and down, so as to adjust laser according to different requirements, thereby realizing different marking effects, the operation is convenient and fast, the accuracy is higher, and the labor is saved, because the top end of the machine body 1 is fixedly connected with the storage cylinder 31, a large number of mobile phone shells can be stacked and stored through the arrangement of the storage cylinder 31, thereby facilitating the subsequent continuous feeding and increasing the marking efficiency, because the protection plate 32 is rotatably connected with the fixed seat 33 through the rotating shaft 34, when the stacked mobile phone shells need to be put in, only the protection plate 32 needs to be rotated to be opened, thereby facilitating the discharging, and because the torsional spring 39b is arranged between the rotating shaft 34 and the fixed seat 33, through the elastic action of the torsional spring 39b, the automatic closing after the protection plate 32 is opened, the labor is saved, and because the first cylindrical gear 37 is fixedly connected with the outer part of the rotating shaft 34 inside the fixed seat 33, the inside of the fixed seat 33 is also connected with a second cylindrical gear 38 in a sliding manner, the first cylindrical gear 37 is meshed with the second cylindrical gear 38, the rack 39 sliding in the fixed seat 33 is also meshed with the second cylindrical gear 38, and the rack 39 is fixed with the pull rod 35, therefore, when a pedal 36 fixed with the pull rod 35 is stepped on externally, the rack 39 can drive the second cylindrical gear 38 to rotate, the second cylindrical gear 38 drives the rotating shaft 34 on the first cylindrical gear 37 to rotate, and the opening of the protection plate 32 can be quickly realized in a foot stepping manner, therefore, the mobile phone shell can be placed better without being opened by hands, and at the moment, the mobile phone shell can be conveniently operated by two hands, before the mobile phone shell needs to be placed, the handle 42 is required to be pulled to pull the sliding block 45 to the topmost end of the sliding groove 41, because the handle 42 and the sliding block 45 can also slide transversely, after the sliding block 45 is pulled to the topmost end, then the handle 42 is slid to the top end transverse groove of the sliding groove 41, at this time, the sliding block 45 can be fixed, namely, the pressing plate 44 fixed with the sliding block 45 is pulled to the top end to be fixed, at this time, the mobile phone shell can be placed, after the mobile phone shell is placed, at this time, the handle 42 only needs to be pulled transversely to the vertical groove of the sliding groove 41, at this time, the sliding block 45 can drive the pressing plate 44 to press the mobile phone shell under the elastic force of the first spring, so that the stacked mobile phone shell can be prevented from toppling over, and the normal blanking of the mobile phone shell can be ensured, because the workbench 52 is fixedly connected to the machine body 1, the pushing block 54 sliding in the storage cylinder 31 and the workbench 52 is connected and fixed with the telescopic rod of the air cylinder 51, when the mobile phone shell stacked in the storage cylinder 31 needs to be loaded, at this time, the air cylinder 51 connected with the external air supply system can be extended, because the pushing plate 55 is arranged on the pushing block 54, the material pushing plate 55 can just push out the mobile phone shell placed at the bottommost end to the marking area, and the front end of the material pushing block 54 protrudes out of the material pushing plate 55, so that in the material pushing process of the material pushing block 54, the material pushing block 54 can firstly abut against the two abutting plates 65, the two abutting plates 65 can move towards the two inner ends of the workbench 52, and the clamping plate 61 is connected with the abutting plates 65 through the connecting rod 64, so that when the mobile phone shell is not pushed to the working area, the two clamping plates 61 are already retracted, the pushing of the mobile phone shell cannot be influenced, when the material pushing plate 55 pushes the mobile phone shell into the working area, the air cylinder 51 is retracted, the material pushing block 54 also performs reset movement, because the length of the material pushing block 54 is smaller than that of the mobile phone shell, when the material pushing block 54 is retracted, the material pushing block 54 firstly releases the abutting against the two abutting plates 65, namely, the two clamping plates 61 can automatically clamp the mobile phone shell under the elastic force of the third spring 63, therefore, the situation of mistaken touch and shaking during the marking of the mobile phone shell is avoided, the marking quality is ensured, when the mobile phone shell is firmly clamped by the clamping plate 61, the material pushing plate 55 on the pushing block 54 moves backwards, the material pushing plate 55 is rotationally connected with the pushing block 54 and can be accommodated in the pushing block 54, and the elastic force of the second spring 56 is insufficient to enable the material pushing plate 55 to drive the mobile phone shell to move, so that the material pushing plate 55 is abutted against the mobile phone shell and is accommodated in the pushing block 54, the pushing block 54 is reset under the driving action of the air cylinder 51 at the moment, subsequent material pushing is facilitated again, continuous reciprocating feeding and material pushing work is realized, manual placing is not needed, the marking efficiency is greatly improved, the first blanking sleeve 71 is rotationally connected to one end of the workbench 52, the blanking work of the pushed mobile phone shell is facilitated, and the second blanking sleeve 72 is further slidably connected to the inside of the first blanking sleeve 71, therefore, the blanking distance can be prolonged or shortened according to the actual material receiving condition, the machine body 1 is further fixed with the stand column 81, the inside of the stand column 81 is connected with the sliding sleeve 83 in a sliding mode, the sliding sleeve 83 can be locked and fixed through the fixing bolt 82, and the fixing column 84 fixed on the sliding sleeve 83 can slide in the positioning groove 85 of the side wall of the first blanking sleeve 71, so that the angle of the first blanking sleeve 71 can be adjusted by adjusting the height of the sliding sleeve 83, and the machine body is convenient to be applicable to different blanking environments.
